Michael Bolin aca781b3a7 fix: rename is_azure_responses_wire_base_url to is_azure_responses_provider (#17965)
## Why

While reviewing https://github.com/openai/codex/pull/17958, the helper
name `is_azure_responses_wire_base_url` looked misleading because the
helper returns true for either the `azure` provider name or an Azure
Responses `base_url`. The new name makes both inputs part of the
contract.

## What

- Rename `is_azure_responses_wire_base_url` to
`is_azure_responses_provider`.
- Move the `openai.azure.` marker into
`matches_azure_responses_base_url` so all base URL marker matching is
centralized.
- Keep `Provider::is_azure_responses_endpoint()` behavior unchanged.

## Verification

- Compared the parent and current implementations.
`name.eq_ignore_ascii_case("azure")` still returns true before
consulting `base_url`, `None` still returns false, base URLs are still
lowercased before marker matching, and the same Azure marker set is
checked.
- Ran `cargo test -p codex-api`.

codex-api

Typed clients for Codex/OpenAI APIs built on top of the generic transport in codex-client.

  • Hosts the request/response models and request builders for Responses and Compact APIs.
  • Owns provider configuration (base URLs, headers, query params), auth header injection, retry tuning, and stream idle settings.
  • Parses SSE streams into ResponseEvent/ResponseStream, including rate-limit snapshots and API-specific error mapping.
  • Serves as the wire-level layer consumed by codex-core; higher layers handle auth refresh and business logic.

Core interface

The public interface of this crate is intentionally small and uniform:

  • Responses endpoint

    • Input:
      • ResponsesApiRequest for the request body (model, instructions, input, tools, parallel_tool_calls, reasoning/text controls).
      • ResponsesOptions for transport/header concerns (conversation_id, session_source, extra_headers, compression, turn_state).
    • Output: a ResponseStream of ResponseEvent (both re-exported from common).
  • Compaction endpoint

    • Input: CompactionInput<'a> (re-exported as codex_api::CompactionInput):
      • model: &str.
      • input: &[ResponseItem] history to compact.
      • instructions: &str fully-resolved compaction instructions.
    • Output: Vec<ResponseItem>.
    • CompactClient::compact_input(&CompactionInput, extra_headers) wraps the JSON encoding and retry/telemetry wiring.
  • Memory summarize endpoint

    • Input: MemorySummarizeInput (re-exported as codex_api::MemorySummarizeInput):
      • model: String.
      • raw_memories: Vec<RawMemory> (serialized as traces for wire compatibility).
        • RawMemory includes id, metadata.source_path, and normalized items.
      • reasoning: Option<Reasoning>.
    • Output: Vec<MemorySummarizeOutput>.
    • MemoriesClient::summarize_input(&MemorySummarizeInput, extra_headers) wraps JSON encoding and retry/telemetry wiring.

All HTTP details (URLs, headers, retry/backoff policies, SSE framing) are encapsulated in codex-api and codex-client. Callers construct prompts/inputs using protocol types and work with typed streams of ResponseEvent or compacted ResponseItem values.
